Alien Soldier is a 1995 run-and-gun game by Treasure for the Sega Genesis. While it shares some similarities with other run-and-guns, the focus here is on lightning fast reflexes instead of using the strongest weapon avaliable. You play as Epsilon-Eagle, a cybernetic birdman who fights against the rogue organization Scarlet, travelling throughout the galaxy and leaving large amounts of carnage in your wake.The plot, if it even matters, concerns a criminal organization of genetically-engineered beings called "Scarlet" who terrorized the planet Sierra. Their members are able to live within humans, animals and machines via a parasitic ability. Epsilon-Eagle, the leader of Scarlet, was ambushed by a team of Sierrans with super powers, and thrown into the space-time continuum. The new leader of Scarlet, Xi-Tiger, was hated by his own men for being too ruthless compared to Epsilon, and as such he wanted to destroy Epsilon once and for all. Xi-Tiger attacked a Sierran research laboratory where he sensed Epsilon in the body of a boy. He took a random girl hostage so as to force Epsilon to come out. Epsilon, instead, transformed from a boy into a cyborg birdman. However, Epsilon's good human sidebegan to overcome his evilness and made him want to fight the demons. This annoyed Xi-Tiger, who killed the girl before running away. The plot actually makes even less sense as it proceeds, with the planet blowing up and Epsilon ending up fighting a giant mechanical lion called Z Leo without the player really having any idea who he is or why this is necessary.Epsilon's a handy fellow, able to carry four weapons at a time. Each one of these can be chosen from a list at the start of the game:
Lancer Force, a better laser that uses more ammunition. The other boss-killer.
Epsilon-Eagle has several unique abilities at his disposal, including a dash-like teleportation, levitation, a bullet-neutralizing shield, as well as a Ceiling Cling. All of these require the player to be on their toes, as waves of enemies and powerful bosses come after them.
This work contains examples of:
0% Approval Rating: Xi-Tiger, the new leader of Scarlet. He's hated by his own comrades due to being too ruthless towards the Sierrans, tries to kill off his old deposed leader, but what takes the cake is that he takes an innocent girl hostage AND KILLS HER. When you fight him, he literally transforms himself into a monster tiger.
Airborne Mook: Those goddamned flies that flew round in random circles, then shot at you and kamikazed into you. Hope you have the Homing Force ready...
Those bomb-dropping birds can be a pain in the ass too.
As well as those things that travel in long lines and explode into suicide bullets, found at only one part of the game. A smart player can use the Bullet Catch ability to turn their bullets into health.
All There in the Manual: The confusing plot, such as it is, is outlined there. Did you know children can turn into birdmen if they're posessed and pissed off enough, or that a clone of a birdman might be a giant metal bird with laser wings?
The properly-translated version of the rom does tell the story properly in the intro.
Some of the enemies are even more bizarre: they have a different weak spot against different weapons. For example, Wolfgunblood's head is weak to fire weapons and the Buster Force, while Garopa's head is weak to the Lancer Force. Though Homing Force says the target on Wolfgunblood is somewhere else entirely.
Boss Arena Urgency: Back Stringer. If the baby spiders pull the remains of the previous boss, Viblack (a.k.a. the platform you're standing on), to the bottom of the screen until it disappears, you'll keep falling into the bottomless pit OVER AND OVER AGAIN (read: Game Over)!
Boss Game: Stages are generally short, with only a handful of enemies at a time in the spaces between one boss and the next.
Bottomless Magazines: Averted. Limited ammunition for your strongest weapons is one of the largest threats you face. It only recharges when you collect a new weapon, or switch to a different one.
Bullet Catch: Epsilon-Eagle's main defensive ability. Hit the shoot button twice to create a small forcefield that turns enemy fire into health. Make sure you don't do this with a Lancer equipped, though, since doing so wastes its already-limited ammo and cancels the shot to boot.
Came Back Wrong: You know that girl that died in your failed attempt to save her? Not only does she became one of the game's bosses, she's freaking SevenForce.
Cameo: Melon Bread (referred to in this game as "Jampan") and Seven Force, both markedly different from their Gunstar Heroes incarnations.
Cast from Hit Points: At full health (health bar flashing white), Epsilon-Eagle can utilize a fiery teleport-dash which destroys any Mooks in its path as well as heavily damaging bosses. However, this attack does come at the cost of a few hit points, so you need to collect the rather frequently-dropped health powerups.
Cherry Tapping: Run out of ammo from one of your weapons and it becomes a weak-as-hell "yellow short-range smoke" shot thing. You can still use it to defeat bosses. It's one of three ways to damage the Final Boss (the other two being shot reflection and your fiery dash which you can only use once against him).
Idiosyncratic Difficulty Levels: Superhard and Supereasy. Even though the latter is anything but; enemies are less tough, you receive unlimited continues (via a password system) and get an option to slow the game speed down.
Self-Imposed Challenge: During the initial weapon selection and configuration, the player has the option to make all information about his health, ammunition and boss health into '???', essentially preventing the player from tracking how much damage was taken or dealt or how much ammo they have left.
Sequential Boss: Seven Force, which only has six forms (including the human form she starts in). This is because the "Seven" is a reference to the Mode 7-style rotation effects the boss showcases, not the number of forms it has.
